Significance Synthetic auxin herbicides intersect basic plant developmental biology and applied weed management. We investigated resistance to 2,4-D in the Australian weed Sisymbrium orientale (Indian hedge mustard). We identified a mechanism involving an in-frame 27-bp deletion in the degron tail of auxin coreceptor IAA2, one member of the gene fa...
Chapter
Fungal diseases such as powdery mildew and bunch rots reduce yield and quality of grapes and affect chemical and sensory properties of wine. The effects of powdery mildew, downy mildew, botrytis bunch rot, and ripe rot on grape and wine quality are reviewed. Approaches to detection and quantification of fungal contamination are examined, including...

A description of the fungus (E. necator), its host range, biology and ecology, symptoms caused by fungus and disease management. Published by the Australasian Plant Pathology Society
Article
Background and Aims: Powdery mildew (Erysiphe necator) reduces the quality of winegrapes, and objective methods for assessment are required. Mid-infrared spectroscopy and fatty acid analysis were investigated for rapid diagnosis of affected berries. Methods and Results: Colonisation by E. necator reduced berry diameter and mass and increased the su...

Background Hyperspectral imaging is an emerging means of assessing plant vitality, stress parameters, nutrition status, and diseases. Extraction of target values from the high-dimensional datasets either relies on pixel-wise processing of the full spectral information, appropriate selection of individual bands, or calculation of spectral indices. L...

Six new species of Fusarium associated with soil and plant hosts from ecosystems of minimal anthropogenic disturbance in Australia are described. Fusarium coicis from Coix gasteenii, F. goolgardi from Xanthorrhoea glauca, F. mundagurra from soil and Mangifera indica, F. newnesense from soil, F. tjaetaba from Sorghum interjectum and F. tjaynera from...
Article
Full-text available
Research was undertaken to identify Fusarium spp. associated with an endemic wild rice (Oryza australiensis) community in northern Australia and determine the incidence of species reported as pathogens of tropical grain crops. A total of 92 isolates representing six Fusarium species were recovered from O. australiensis. Taxa were delimited based on...

Root samples of cereals (oats, wheat, barley, maize and sorghum), vegetables (garlic, onion, pepper, cucumber, pumpkin, carrot and tomato), industrial plant (soya bean) and weeds (Johnson grass, barnyard grass and green bristle-grass) collected in different agroecological conditions in Serbia were analysed for the presence of Pyrenochaeta terrestri...
Article
Full-text available
Rot symptoms that Pyrenochaeta terrestris causes on the root of each internode of maize hybrids belonging to different maturity groups, as well as the impact of growing conditions (substrate, temperature and light) on the properties of the colony and the pycnidial formation of this fungus were studied. The large number of symptoms was obtained by v...

Full-text available
Pathogenicity of P. terrestris was determined by the Knop’s medium slants method intest tubes. Isolates originated from the roots of maize (Zea mays L.), barley (Hordeum vulgareL.), Johnson grass (Sorghum halepense Pers.), sorghum (Sorghum bicolour (L.) Moench.), garlic(Allium sativum L.), onion (Allium cepa L.), barnyard millet (Echinochloa crus-g...
Article
The frequency and incidence of Pyrenochaeta terrestris and symptom type on the roots of each internode of four maize hybrids of different maturity groups were studied 70 days after sowing. The fungus developed in the roots of all developed internodes (from the primary to the sixth or seventh internodes of all tested hybrids). The average frequency...

Full-text available
Two new species of Fusarium associated with Australian indigenous grasses in natural ecosystems are described as F. lyarnte and F. werrikimbe on the basis of morphology, DNA fingerprinting and phylogenetic analysis of EF-1α and β-tubulin sequence data. Isolates of these species were initially recovered from soil in the McGraths Creek area of centra...
Article
Full-text available
Fusarium species associated with plants as pathogens, saprobes and endophytes in Australia are listed with notes on their pathogenicity and toxicity provided. A list of Fusarium species not known to occur in Australia also is provided and their quarantine significance evaluated. KeywordsFusarium–Biosecurity–Quarantine–Plant disease–Mycotoxins–Aust...
Article
Full-text available
Recent revisions in taxonomy have led to significant changes in our understanding of the Fusarium species associated with sorghum worldwide. To reassess the Fusarium species associated with stalk rot of grain sorghum in Australia, a survey was conducted in two different agroclimatic areas in the northern grain belt of eastern Australia (Goondiwindi...
Conference Paper
Toxicological profile and fertility of twenty four isolates of P. proliferatum, isolated from maize plants grown in different localities across Serbia, were analyzed. Seven investigated isolates were MATD-1 and seventeen were MATD-2. All isolates produced FB1 at a relatively high level (up to 3950 mu g g(1)), except for MRIZP56 which did not produc...

Full-text available
The determination of Exserohilum turcicum virulence factors and resistance responses of three sets of maize inbred lines (four differential, eight isogenic and 22 commercial inbreeds) to three isolates of this pathogen under greenhouse conditions were studied. The maize inbreeds were selected according to previous testing of resistance based on les...

Little information is available on Fusarium associations with non-crop hosts in grasslands despite extensive studies on Fusarium species in agricultural systems. The Fusarium species associated with the Australian indigenous grass, Austrostipa aristiglumis, including the key pathogenic species Fusarium pseudograminearum, F. thapsinum and Gibberella...

Fusarium proliferatum can occur on a wide range of economically important vegetable plants but its role in disease is not always well established. In 2000 and 2001, from forty-one field samples of wilting onion and garlic plants in Serbia, F. proliferatum as the predominant fungal species was isolated from root and bulbs. Seventy isolates were firs...

Fusarium graminearum (teleomorph: Gibberella zeae) is widely spread pathogen of cereals and maize. Fast and reliable determination of this parasite and analysis of its DNA molecules is possible by amplification in polymerase chain reaction (PCR). DNA isolation is an operation necessary for amplification by PCR that takes a lot of time and increases...

The pathogenic characteristics of 10 isolates of Bipolaris species and two isolates of Exserohilum species, isolated from the leaves of six weed species of the family Poaceae (Tab. I) have been studied. Weeds (Cynodon ductylon, Panicum cruss-galli, Setaria glauca, Setaria verticillata, Setaria viridis and Sorghum halepense) with expressed symptoms...

The formation of conidia in Phaeocytostroma ambiguum on different media and conditions was investigated in this study. Carnation leaf agar (CLA) and a 12 h photoperiod (24/18 degrees C) provided excellent conditions for the promotion of rapid formation of both alpha (alpha) and beta (beta) conidia in a number of P. ambiguum isolates. The dimensions...

This MSc project aimed to: (i) identify obligate and facultative fungal species associated with mono - and dicotyledon weed species in maize crops in Zemun Polje (Serbia) and (ii) test pathogenicity of Bipolaris spp., Exserohilum spp. and Gloeocercospora sorghi from weeds on the hosts, maize and sorghum. Pathogenicity of G. soghi was only tested on Johnsongrass and sorghum.
